| Abstract |
Proving the quality and efficiency of energy conservation and emission reduction in the construction industry and providing high-quality products and services are important forces in achieving the goal of 'double carbon'. They play a crucial role in the sustainable development of human society and nature and are the typical embodiment of the high-quality development of Chinese modernization. This paper analyzes the proportion and importance of China's construction industry policy system, spatial characteristics, energy consumption, and carbon dioxide emissions in achieving the 'double carbon' goal. The life cycle assessment (LCIA) method identifies that the materialization, operation, and use stages are the key stages of the whole process and the influencing factors of energy consumption and carbon emissions. Using the analytic hierarchy process (AHP) method, this paper explores and creates China's construction industry's '1 + 5 + N' high-quality development index system by proposing four stages: top-level design period, deep development period, consolidation achievement period, and summary planning period. These stages aim to facilitate quality improvement, efficiency enhancement, innovation drive, and whole life cycle sustainability. This system's principles are 'systematic planning, one type of one policy, collaborative efforts, safety, and economy'. The proposed system aims to enhance the policy and standard system, strengthen the implementation of policy tools, increase the investment and application of energy-saving and efficiency-increasing technologies, improve the development of energy consumption and carbon emission monitoring systems and platforms, reinforce green finance, standardize information disclosure, accelerate the renovation of outdated infrastructure, and intensify efforts to promote and guide green consumption, lifestyles, and production methods. |
